3 Claims. (Cl. 257-137) This invention relates as indicated to appararatus comprising the casing I is preferably tus for heating rooms. More particularly it formed of sheet metal and of substantially reccomprises the utilization of a layer of relatively tangular shape, and preferably of substantially colder air projected above a zone of heated air greater length than height. Said casing is pref- 5 in a substantially horizontal direction so as erably closed on all sides excepting at the front 5 to retard the heated air from rising to a higher thereof where it is provided adjacent its lower level and thus to secure more effective distribuportion with an inlet opening 2 which may be tion of the heated air throughout the lower in the form of an ornamental grille.

As is clearly shown in the drawing, the appa- Obviously various modifications may be made 55 in the construction of the air heating and circulating device above described, butit has been found that a device of substantially the character illustrated will very satisfactorily distribute heated air into a room and secure a more eicient disposition of the heated air thanis possible with other types of apparatus. It will be noted that the passageway for the cold air is of much smaller cross-sectional area than that of the heated air. It will also be noted that the opening adjacent the discharge outlet for the heated air is somewhat constricted so that a greater heating effect may be obtained on the air passing through the larger passageway and the heated air carried beneath the layer of cold air discharged through the opening I5 at the top of the casing. A

With the apparatus just described, the cold air adjacent the oor of the room to be heated will be drawn into the fan housing and projected upwardly through the respective passageways for the cold airY layer and the heated air layer. The same fan will supply both air columns and will force the separated portions of air through the outlet opening at the top of the casing. As stated, the layer of cold air projected labove the heated air will 'serve as a means for retarding the upward movement of the warmer air and will cause such zone of warmer air tornove substantially horizontally across the room before it intermingles with the counter-currents of air, which will cause it to rise toward the ceiling. In this manner the air adjacent the lower portion of the room will receive heat from the column of heated air emerging from the casing and the air within the room will be maintained at a more uniform temperature throughout its area than where the heated air is allowed to rise directly to the ceiling without the controlling and retarding influence of the layer of relatively colder air.

Other modes of applying the principles of my invention may be employed instead of the one explained, change being made as regards the means and the steps herein disclosed, provided those stated by any of the following claims or their equivalent be employed.

I therefore particularly point out and distinctly claim as my invention:

1. A heating apparatus comprising a casing including rear and top Walls, having an inlet opening adjacent its base and an outlet opening adjacent its top, an internal wall positioned in adjacent relation to the rear wall of the casing, and provided with an upper forwardly extended portion positioned in adjacent and spaced relation to the top wall of the casing, thereby forming a cold air passage between said internal wall and the rear and top walls of the casing and a heated air passage forwardly of said internal wall, a heat unit disposed in said heated air passage, yand a blower positioned adjacent the lower extremity of said internal wall and discharging into both of said passageways, said heat unit comprising a plurality of spaced vanes positioned in vertical planes and extending lengthwise of the casing.

2. In a heater, an elongated casing provided in the upper region ofits forward wall with a discharge opening, a blower in the lower region of the casing, discharging upwardly, and a heat unit interposed between said blower and the discharge opening, said unit comprising a plurality of spaced vanes positioned in vertical planes and extending lengthwise of the casing.

3. In a heating apparatus adaptable for installation in a wall, an upright casing including front, rear and top walls, having an inlet opening adjacent its base and an outlet opening in its front wall adjacent its top, an internal wall positioned in adjacent spaced relation to the rear wall and provided with an upper forwardly extended portion positioned in adjacent spaced relation to the top wall and terminating just short of the plane of said outlet opening, thereby forming a cold air passage between vsaid internal wall and the rear and top walls of the casing and a heated air passage forwardly of said internal wall, entirely insulated from the rear and top walls by said cold air passage, a heat unit of a type which is capable of producing re hazard temperatures, located in said heated air passage, and a blower positioned adjacent the lower extremity of said internal wall and discharging into both of said passageways.
